Asthma causes recurring periods of wheezing a whistling sound when you breathechest tightness, shortness of breath, and coughing. The coughing often occurs at night or early in the morning. Asthma affects people of all ages, but it most often starts during childhood. In the United States, more than 25 million people are known to have asthma.
Overview To understand asthma, it helps to know how the airways work. The airways are tubes that carry air into and out of your lungs. People who have asthma have inflamed airways. The inflammation makes the airways swollen and very sensitive. The airways tend to react strongly to certain inhaled substances.
When the airways react, the muscles around them tighten. This narrows the airways, causing less air to flow into the lungs. The swelling also can worsen, making the airways even narrower. Cells in the airways might make more mucus than usual.
Mucus is a sticky, thick liquid that can further narrow the airways. This chain reaction can result in asthma symptoms. Symptoms can happen each time the airways are inflamed. Asthma Figure A shows the location of the lungs and airways in the body.
Figure B shows a cross-section of a normal airway. Figure C shows a cross-section of an airway during asthma symptoms. Sometimes asthma symptoms are mild and go away on their own or after minimal treatment with asthma medicine.
Other times, symptoms continue to get worse. Asthma attacks also are called flareups or exacerbations eg-zas-er-BA-shuns.
Treating symptoms when you first notice them is important. This will help prevent the symptoms from worsening and causing a severe asthma attack. Severe asthma attacks may require emergency care, and they can be fatal.According to the Scottish Intercollegiate Guidelines Network (SIGN), Ms V was on step 2 in the management of chronic asthma.
She was on MDI. Asthma is a chronic lung disease that inflames and narrows the airways. Your doctor may ask you about related health conditions that can interfere with asthma management.
These conditions include a runny nose, sinus one study of children between the ages of 5 and 11 found that children given the higher doses when their symptoms worsened. There are now many guidelines that provide direction for the diagnosis and management of asthma and chronic obstructive pulmonary disease (COPD).
However, both diseases are still underdiagnosed (or misdiagnosed) and undertreated. There is considerable evidence that treatment with anti-inflammatory.
The treatment summary for Asthma outlines the aims of the management of chronic asthma. The aim is to achieve early control of the condition and to maintain this control by stepping up treatment as necessary and stepping down treatment when control is good.
